Natural Semantic Metalanguage (NSM) is a linguistic theory that proposes a set of universal semantic primes, which are simple, irreducible concepts found in all languages, serving as the foundation for cross-cultural communication and understanding. It aims to break down complex meanings into these basic elements to facilitate clearer and more accurate translations and intercultural dialogue.
Language simplicity refers to the ease with which a language can be learned, understood, and used effectively, often achieved by minimizing complexity and ambiguity in grammar, syntax, and vocabulary. It aims to enhance communication efficiency and accessibility, making it easier for both native and non-native speakers to interact and comprehend information.
